Coil

Coil

Is one of the basic components in the circuit，Mainly used to store magnetic field energy and adjust the relationship between current and voltage in the circuit。
It is made of wire wound in circles，Often wrapped in insulating material to prevent current leakage。

Description

Coil

Inductor coil is an indispensable component in electronic equipment，Its role in the circuit is important and complex。

Its main characteristic is its inductance value through precise design and manufacturing，and proper use and maintenance，Can give full play to the performance of the inductor coil，Provide stability for electronic devices、Efficient operation guarantee。

in circuit，The main function of the inductor coil is filtering、Resonance and energy storage。as a filter，An inductor prevents current of a specific frequency from passing through it，thereby cleaning up the noise in the circuit。

as a resonant element，The inductor and capacitor together form a resonant circuit，Used for frequency selection or oscillation。

as energy storage element，Inductors can store magnetic field energy when current changes，When the current decreases or disappears，This energy can be released again，thereby maintaining the continuity of the current。

application：Communication field、Energy field、auto industry、medical field、Household appliances, etc.。
